WARNING! This image may trigger PINSecurity.

From an analysis of 3.4m PIN code leaked from several data breaches https://informationisbeautiful.net/visualizations/most-common-pin-codes/

A diagonal line of ‘heat’ from bottom left to top right reveals people choosing double digits (2323, 6868 etc). A strong horizontal line at the 19 point shows people using their birth year as a PIN code (1971, 1998 etc). And a large amount of heat in the bottom left shows how people commonly use their birthdate in a MM/DD or DD/MM format. The most common code in the set is 1234.
The Top 20 most common 4 digit PIN numbers, as revealed by an analysis of data breaches, constitute 27% of all PIN numbers. They are 1234, 1111, 0000, 1212, 7777, 1004, 2000, 4444, 2222, 6969, 9999, 3333, 5555, 6666, 1122, 1313,8888,4321,2001,1010

@infobeautiful Which just proves my point that it's a bad idea to let people choose their own PIN. Getting assigned a number randomly is a bit safer. (Although Chip+4-digit-PIN isn't great in the first place: https://murdoch.is/papers/oakland10chipbroken.pdf).

@infobeautiful This is why if you're ever trying to guess a padlock code, you should start at around 1950 and keep incrementing by 1

@infobeautiful I like the single bright dot at 1701 , the registration number for the Enterprise in Star Trek. I once had that assigned as my random PIN on delivery of a new card, I changed it straight away as that's an easy guess for anyone who knows anything about me.

@_thegeoff @infobeautiful Or not. They know you're too smart for that, so it's prolly the last number they'll try. ;)
